6.4 Information for use 使用說明書
6.4.1 General
The user's manual shall include all information regarding the safe operation of the
PDS/CDM/BDM. In particular, it shall identify any hazardous materials and risks of electrical
shock, overheating, explosion, excessive acoustic noise, etc.
The manual should also indicate any hazards which can result from reasonably foreseeable
misuse of the PDS.
6.4.2 Adjustment調整
The user's manual shall give details of all safety-relevant adjustments intended for the user.
The identification or function of each control or indicating device and fuse shall be marked
adjacent to the item. Where it is not possible to do this on the product, the information shall be
provided pictorially in the manual.
Maintenance adjustments may also be described in this manual, but it shall be made clear that
they should only be made by qualified personnel.
Clear warnings shall be provided where excessive adjustment could lead to a hazardous state
of the PDS/CDM/BDM.
Any special equipment necessary for making adjustments shall be specified and described.
6.4.3 Labels, signs and signals 標貼
6.4.3.1 General
Labelling shall be in accordance with good ergonomic principles so that notices, controls,
indications, test facilities, fuses, etc., are sensibly placed and logically grouped to facilitate
correct and unambiguous identification.
All safety related equipment labels shall be located so as to be visible after installation or
readily visible by opening a door or removing a cover.
Where a hazard is present after the removal of a cover, a warning label shall be placed on the
equipment. The label shall be visible before the cover is removed.
Labels shall:
• wherever possible, use international symbols as given by ISO 3864, ISO 7000 or
IEC 60417;
• if no international symbol is available, be worded in an appropriate language or in a
language associated with a particular technical field;
• be conspicuous, legible and durable;
• be concise and unambiguous;
• state the hazards involved and give ways in which risks can be reduced.
When instructing the person(s) concerned as to
• what to avoid: the wording should include “no”, “do not”, or “prohibited”;
• what to do: the wording should include “shall”, or “must”;
• the nature of the hazard: the wording should include “caution”, “warning”, or “danger”, as
appropriate;
• the nature of safe conditions: the wording should include the noun appropriate to the
safety device.
Safety signs shall comply with ISO 3864.
The signal words indicated hereinafter shall be used and the following hierarchy respected:
• DANGER to call attention to a high risk, for example: “High voltage”
• WARNING to call attention to a medium risk, for example: “This surface can be hot.”
• CAUTION to call attention to a low risk, for example; “Some of the tests specified in this
standard involve the use of processes imposing risks on persons concerned.”
Danger, warning and caution markings on the PDS shall be prefixed with the word “DANGER”,
“WARNING”, or “CAUTION” as appropriate in letters not less than 3,2 mm high. The remaining
letters of such markings shall be not less than 1,6 mm high.
6.4.3.2 Isolators隔離裝置
Where an isolating device is not intended to interrupt load current, a warning shall state:
DO NOT OPEN UNDER LOAD.
The following requirements apply to any supply isolating device which does not disconnect all
sources of power to the PDS.
• If the isolating device is mounted in an equipment enclosure with the operating handle
externally operable, a warning label shall be provided adjacent to the operating handle
stating that it does not disconnect all power to the PDS.
• Where a control circuit disconnector can be confused with power circuit disconnectors due
to size or location, a warning label shall be provided adjacent to the operating handle of the
control circuit disconnector stating that it does not disconnect all power to the PDS.
6.4.3.3 Visual and audible signals 視訊與音效訊號
Visual signals such as flashing lights, and audible signals such as sirens, may be used to warn
of an impending hazardous event such as the driven equipment start-up and shall be identified.
It is essential that these signals:
• are unambiguous;
• can be clearly perceived and differentiated from all other signals used;
• can be clearly recognized by the user;
• are emitted before the occurrence of the hazardous event.
It is recommended that higher frequency flashing lights be used for higher priority information.
NOTE IEC 60073 provides guidance on recommended flashing rates and on/off ratios.
6.4.3.4 Hot surfaces熱源警告
Surfaces which can exceed the temperature limits of Table 16 shall be marked with the
warning symbol IEC 60417-5041 (2002-10) (see Annex H). The user’s manual shall also
contain this information.
6.4.3.5 Equipment marking設備標示
The identification of each control or indicating device and fuse shall be marked adjacent to the
item. Replaceable fuses shall be marked with their rating and time characteristics. Where it is
not possible to do this on the product, the information shall be provided pictorially in the
manual.
Appropriate identification shall be marked on or adjacent to each movable connector.
Test points shall be individually marked with the circuit diagram reference.
The polarity of any polarized devices shall be marked adjacent to the device.
The diagram reference and if possible the function shall be marked adjacent to each pre-set
control in a position where it is clearly visible while the adjustment is being made.
